Techniques and systems for providing games of chance with multiple levels of persistent features are disclosed. Some example systems include scatter prize indicators that are each associated with different symbol positions of a game of chance. When a scatter symbol is selected for a given symbol position, the scatter prize indicator associated therewith may be upgraded; selection of a sufficient number of symbol positions may result in a feature game mode being activated. During feature game mode play, scatter symbols are retained after each play of the game until either sufficient consecutive plays occur without any scatter symbols being obtained or until all symbol positions have scatter symbols. In the latter case, the scatter prize indicators are upgraded and play continues. In the former case, the feature game mode concludes. Various enhancements may be triggered based on the number of times that the feature game mode has been activated.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The electronic gaming system of claim 1, wherein the symbol positions in the GUI are arranged in a first pattern and the scatter prize indicators in the GUI are arranged in a pattern that matches the first pattern but is located in a different location from the first pattern.
3. The electronic gaming system of claim 1, wherein the scatter prize indicators in the plurality of scatter prize indicators caused to be presented via the GUI in the one or more displays in (b) are randomly selected.
5. The electronic gaming system of claim 1, wherein each tier of scatter prize indicators corresponds with a different multiplier amount.
6. The electronic gaming system of claim 5, wherein a subset of the tiers of scatter prize indicators includes one or more scatter prize indicators that each correspond with a different multiplier amount and a progressive award.
7. The electronic gaming system of claim 1, wherein each tier of scatter prize indicators corresponds with a different credit amount.
8. The electronic gaming system of claim 1, wherein the one or more memory devices further store additional computer-executable instructions for controlling the one or more processors to, responsive to each performance of (d), cause, for each symbol position in the GUI that displays a selected symbol of the first type of symbol as a result of (d), a credit meter displayed in the GUI to be updated with a corresponding award that is based on the scatter prize indicator associated with that symbol position.
9. The electronic gaming system of claim 1, wherein the first set of the symbol positions also at least excludes the symbol position or symbol positions that displayed a symbol or symbols of the first type of symbol when that instance of the feature game mode was initiated.
11. The electronic gaming system of claim 10, wherein the one or more memory devices further store additional computer-executable instructions for controlling the one or more processors to, responsive to each conclusion of a current round of an instance of the feature game mode due to all of the symbol positions being associated with selected symbols of the first type of symbols, cause a credit meter displayed in the GUI to update to reflect an award in association with the conclusion of that current round of that instance of the feature game mode, wherein the award is based on the scatter prize indicators that are associated with all of the symbol positions at the conclusion of that current round of that instance of the feature game mode.
12. The electronic gaming system of claim 1, wherein the one or more memory devices further store additional computer-executable instructions for controlling the one or more processors to cause a credit meter displayed in the GUI to update to reflect an award as part of (i), wherein the award is based on the scatter prize indicators that are associated with the symbol positions in the GUI that display symbols of the first type of symbol at the conclusion of that instance of the feature game mode.
15. The electronic gaming system of claim 14, wherein the one or more memory devices further store additional computer-executable instructions for controlling the one or more processors to cause, responsive to each determination that the second feature game mode enhancement condition has been met, the GUI to be updated to upgrade at least a first number of the scatter prize indicators to the next higher tier of scatter prize indicator, wherein the first number is greater than a number of scatter prize indicators, if any, that the GUI is caused upgraded responsive to the first feature game mode enhancement condition being met.
16. The electronic gaming system of claim 14, wherein the one or more memory devices further store additional computer-executable instructions for controlling the one or more processors to cause, responsive to each determination that the second feature game mode enhancement condition has been met, the GUI to be updated to display a symbol of the first type of symbol in at least a first number of symbol positions that did not display symbols of the first type of symbol at the start of the current instance of the feature game mode, wherein the first number is greater than a number of symbol positions, if any, that are to be caused to display symbols of the first type of symbol responsive to the first feature game mode enhancement condition being met.
17. The electronic gaming system of claim 1, wherein the one or more memory devices further store additional computer-executable instructions for controlling the one or more processors to, in performing (g), select and display the symbol for each symbol position in the first set independently of the selection and display of the symbol for any other symbol position in the first set.
